Thanissaro Bhikkhu wrote:The insight of a stream-enterer into the truths of causality on the one hand, and of the Deathless on the other, is accurate as far as it goes, but it does not equal the intensity of the insight of the arahant — one who has reached the final level of awakening. The differences between the two are suggested in the following simile.

Metta,Retro.

If you have asked me of the origination of unease, then I shall explain it to you in accordance with my understanding: Whatever various forms of unease there are in the world, They originate founded in encumbering accumulation. (Pārāyanavagga)

Exalted in mind, just open and clearly aware, the recluse trained in the ways of the sages:One who is such, calmed and ever mindful, He has no sorrows! -- Udana IV, 7

I have read yours links and I have found this term paccavekkhaṇañāṇa in the texts provided by mikenz66. I was investigating about this pali term. However, while I'm able to find enough descriptions about "reviewing knowledge", I cannot find definitive explanations about how to use that in a proper way.

And the practice of meditation here refers to the practice of insight meditation (vipassanānuyogo)[16] up to the vicinity of the knowledge of conformity and change-of-lineage (yāva anulomaṃ gotrabhusamīpaṃ)[17], that is to say, up to the knowledge of equanimity towards formations (saṅkhārupekkhāñāṇaṃ)[18], the highest knowledge arising in the cognitive process of the mundane path.[19][...]"What is called the reviewing knowledge is the reflection undertaken by the disciples, soon after they attained each of the four supra-mundane Fruitions (lokuttaraphala)."** ( 6. 2 / 6.3. - http://www.budsas.org/ebud/catu/catu06.htm )

"Soon after".. Can it means the bhikkhu should avoid the review after long time because it would not be paccavekkhaṇañāṇa?. Or another question: In the case that we believe the paccavekkhaṇañāṇa can arise after a long time, It would be right reviewing saṅkhārupekkhāñāṇaṃ directly or there is an strict order in the way to insight until saṅkhārupekkhāñāṇaṃ?Also, logically in the case that we believe the paccavekkhaṇañāṇa cannot arise after a long time, then any review cannot be paccavekkhaṇañāṇa, and here I cannot understand what's the real purpose of the explanation.

These types of things are the things that I cannot find. It sounds like: "...in the path to fruition it arises 1,2,3,4... And these things are a, b, c, d. See you at the next level". I don't know if the practice continues as always and the bhikkhu should avoid any reviewing because it is not paccavekkhaṇañāṇa but just an attachment to distorted images.

Do you know any commentary or text which explain these things with a more practical focus and not so focused in theoretical descriptions?. Or maybe it doesn't exists? Or I'm in a total mess?

thanks for any idea or help,

*** Thank you retrofuturist. Additionally to these Thanissaro words, while I was searching in the net I have found this text from Mahasi Sayadaw including several examples to help in clarifying insights: In "WRONG LIBERATION (MICCHĀVIMUTTI)" and forward: http://static.sirimangalo.org/mahasi/Sa ... 0Sutta.htm

And thank you very much for your answers and links, they can save a lot of time. This board is a very useful resource for the whole world. Hope you can keep this good work!
